Angelo Heilprin was born at Sátoraljaújhely, in the Zemplén County of the Kingdom of Hungary. His family was Jewish. He arrived in the United States from the Austrian Empire with his father Michael and his brother Louis in 1856. He went back to Europe in 1876 for two years to complete his education. He studied at the Royal School of Mines, London, at the Imperial Geological Institution of Vienna, and at Florence (where he had his only formal training in painting) and Geneva; he also went to Hungary, where he mountaineered in the Carpathians, and to Poland where he visited family for six months. He then became professor of invertebrate paleontology and of geology at the Academy of Natural Sciences, Philadelphia (1880–1900), curator of the museum of that institution (1883–1892), professor of geology at the Wagner Free Institute of Science in Philadelphia (1885–1890); and he was the first president of the Geographical Society of Philadelphia, serving for seven years. In 1883, he was elected as a member to the American Philosophical Society. Also a painter, Heilprin exhibited Autumn's First Whisper at the Pennsylvania Academy of the Fine Arts in 1880, and Forest Exiles at the Boston Museum of Fine Arts in 1883. In 1902 he founded the American Alpine Club. In 1904, he was appointed as a lecturer at Yale.

He visited Florida, the Bermudas, Mexico, Greenland and Martinique while also devoting work to his more immediate surroundings. His mountaineering skills were put to use many times in his scientific work. In 1886, Heilprin undertook an expedition to the then little-known west coast of Florida. In 1887 he went to the Bermudas with members of his classes to study coral reefs, confirming Charles Darwin's 1842 views expressed in The structure and distribution of coral reefs. In 1888, Heilprin was in Mexico, where he ascended volcanos: Ixtaccihuatl, Nevado de Toluca, Pico de Orizaba and Popocatepetl, establishing their altitudes with barometric measures. He also shed light on questions about the geology of the Yucatan and the coral reefs of the western Gulf of Mexico. En 1891 Heilprin embarked with Robert Peary on an expedition to Greenland organized by the Academy of Natural Sciences. Peary was the leader of the north-bound expedition, which was to prove that Greenland is an island. Heilprin headed the "Western Expedition" comprising half a dozen scientists. The scientists collected data then returned to the U.S., while Peary remained in Greenland. But the next year Heilprin was back to Greenland, leading the "Peary relief expedition". In 1902, when Montagne Pelée in Martinique erupted, reducing the city of Saint-Pierre to ashes, Heilprin was one of the first scientists to arrive to the site. His works, photographs and eyewitness account of the phenomena and their consequences are unique. He was the first geologist to ascend a side of the crater. He revisited it in 1903 and in February 1906 descended into the crater itself.

• In 1976 the American Alpine Club established a yearly "Angelo Heilprin Citation". • The Heilprin Glacier, having its terminus at the head of the Inglefield Fjord in NW Greenland, was named after him by Robert Peary.

• Boana heilprini • Cyanocorax heilprini (the azure-naped jay), a species in the family of Corvidae, was named after him. • Hypsiboas heilprini also bears his name.
